Key Responsibilities

• Take ownership of the development and optimisation of quantitative trading strategies for dispatching flexible assets across intraday, day-ahead, balancing, and ancillary service markets.

• Collaborate closely with traders to validate hypotheses, back-test strategies against real P&L, and incorporate trader intuition into model design.
• Scale strategies across geographies and asset classes, adapting to local market rules, grid codes, and asset-specific technical constraints (e.g., degradation, ramp rates, state-of-charge).
• Design and maintain robust data pipelines that feed real-time and historical market, weather, and asset data into modelling and decision engines.
• Monitor live strategy performance, detect drift or anomalies, and implement rapid feedback loops for continuous improvement.
• Communicate results clearly to both technical and non-technical stakeholders, translate complex model outputs into trading insights and strategic recommendations.
